SUPPORT AND RECEPTACLE FOR ELECTRICAL DEVICES.

. Specification of Letters Patent.

Patented Dec. 1, 1914.

Application filed November 15, 1911. Serial No. 660,455.

' ject of the King of Norway, residing at Milwaukee, in the county of Milwaukee State of Wisconsin, have invented IieW and useful Im rovements in Supports and Receptacles or Electrical Devices, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawing, forming a part of this specification. My invention relates to supports and receptacles for electrical devices.

It has among its objects to provide an improved support and receptacle for electrical devices of an exceedingly simple and strong construction which may be manufactured at small expense, and which may be assembled very readily and quickly.

A further object of my invention is to provide an improved device which in one of its forms is especially adapted to contain and support electric switch devices.

Other objects and advantages of my improved construction will hereinafter appear. In the accompanying drawings I have, for purposes of illustration, shown one form which my invention may assume in practice.

My invention is not, however, limited to this form, but may assume other forms.

In the views of these drawings: Figure 1 shows a side elevation of the receptacle. Fig. 2 shows a central sectional view through the same and the support with the object to be inclosed schematically illustrated. Fig. 3 shows a sectional view on line 33 of Fig. 2. Fig. 4 shows a perspective view of a modified form of support.

In these drawings I have, for purposes of illustration, shown my improved receptacle and support applied to use as an inclosing and supporting means for a feed through snap switch mechanism. Obviously, however, it may be adapted to contain and support other devices. I have shown a two part shell having an upper part 1 arranged to be received telesco ically in the slightly enlarged end 2 of a 0W8! shell member 3. In a-preferred'form thea two parts land-8 and are preferably substantially cylindrical in cross-section throughout the greater part of their lengths, and are rounded at their en'ds. Obviouslyyhowever, the shells may be of any desired shape other than that shown. In a preferred form the ends of the shells 1 and 3 are provided with openings arranged to receive bushings 4 which are preferably 'threaded on their shanks as at 5, and provided with an enlarged head which, when the threaded portionof the bushing is screwed into the shell, is arranged to fit snu ly around the edges of the opening. As illustrated inv Fig. 2, these bushings are provided with a central opening 6. In a referred form these bushings are made 0 insulating material. However, they may, if desired, be made of metal.

A supporting member or bracket is preferably so arranged that it engages a support at the upper part of the shell and extends along within the shell to the bottom of the same where it engages a similar support. In Figs. 2 and 3 have illustrated one form which this supporting member or bracket 7 may assume in practice. As shown in these figures, the supporting member 7, is preferably provided with perforated ends 8 which are threaded to permit them to fit over the threaded ends of the bushings 4. In a preferred construction, these ends, when assembled, bear firmly against the inner surface of the outer shell. Between the ends of the supporting member it is preferably bcnt outward to form a body portion.

which, depending upon the shapeof the receptacle in which it is carried or the use to which it is adapted, mav assume any desired shape. If desired, suitable insulating linings 9 may be carried within one or more of the I though it is obvious that other devices than switch mechanisms or other types than the push button type may be used, if desired. In the construction shown the push button 12 of the switch mechanism extends through suitable perforations or slots in one or more of the shells which may be located in any desirld position. I

InFig. 4 I have illustrated a modified form of a supporting member. In this figure I have shown a supporting member pro-,

vided with perforated ends 8, but with curved body portions 7 arranged on each side of the ends 8. In a preferred form these ends are provided with internally screw-threaded shoulders extending into the frame, as shown in the drawing. If desired, the supporting members shown in Fig. 1 may be provided with similarly shaped ends. \Vhen such a device is mounted in a shell, the two connecting body portions between the ends 8 are preferably arranged so that they pass along the inner walls of the receptacle in a similar manner to the body portion of the support shown in Fig. 2. Ohviously, as in the previous construction, these body portions may be made in anv shape and adapted to use with a receptacle of any form. If desired. they may be adapted to hold one or more devices, as for 111- stance, switch devices, in the manner that the support shown in Fig. 1 may be used. By the use of this double supporting member I am able to increase the stability of the support where necessary without the necessity for using two of the single supports.

When it is desired to assemble my improved receptacle and support, all that it is necessary to do is to insert the support 7 within one of the shells and screw the bush ng into place. The other shell may then be readily attached in a similar manner to the other end of the support. By my improved construction, I am able to provide an improved receptacle and support wherein the strain of supporting the switch mechanism is entirely removed from the parts of the receptacle, so that there is no tendency to separate these parts or to interfere with the operation of the switch mechanism. For instance,'my improved construction may be adapted to use as a casing and support for a feed through switch. in such a construction the conductors would be passed down through the opening (3 in one bushing and attached to one or more of the terminals of a switch mechanism 10, the other ends of the same passing out, through the other end of the lower bushing 4.

By my improved construction I have provided an exceedingly simple and rugged receptacle and support which may be made up ina wide variety otforms. Bv the use of my improved supporting member, I am able to effectually do away with any possibility of the separation t the parts of the casing, since this supporting member connects and serves to hold these parts together. Further, the supporting member serves as a support for the switch mechanism and may be constructed in such forms that switch mechanisms of Widely diti'erent types and their insulating supports may be readily attached to the same. If desired, casings of widely different types may be used with this support and in some constructions the support may be used without a casing. Further, my improved construction is an exceedingly simple one, which may be readily and cheaply manufactured at small expense. By my improved construction and arrangement of parts, I am able to provide a receptacle which may be readily and quickly assembled and disassembled, as desired, and which is well adapted to withstand long use in service.

\Vhile I have in this application described, for purposes of illustration,-one specific form which my invention may assume in practice, I do not wish to be limited to this form, but rather wish toinclude within the scope of this application all of those forms of my invention falling within it spirit.

lVhat I claim as new and desire to secure by Letters Patent of the United States is:

1. In combination, a two-part casing, an insulating lining therefor, and means interposed between said lining and said casing and connecting the ends of the latter for holding the parts thereof together.

2. In combination, a two-part casing. an insulating lining therefor, a metal bracket interposed between said lining and said casing and holding the parts of the latter together, and a transvcrsmly extending device supported by said bracket and supporting said lining.

3. In combination, a two-part .flfill'lfl' having a conductor opening, an insulating lining for said casingQa threaded insulating bushing extending through said conductor opening, and a thin metal bracket shaped to lie adjacent an interior wall of said casing and attached at one end to said bushing t'or holding the parts of said casing together and having means to support said lining.

4. In a feed through switch receptacle, in con'ibirmtion, a two part casing the parts thereof being provided with opposite condoctor op nings, a metal bracket within said casing shaped to lie adja ent a wall thereof, said bracket having threaded openings registering with said casing openings, and insulating bushings extending through said casing openings and threading through said bracket openings to clamp the parts of said casing together and against said bracket, said bushings also constituting alined passages for a conductor.

5. In a receptacle, a two-part casing having its parts arranged to fittogether telescopically, bushings carried in the ends of said parts and a bracket connecting said bushings and holding together said part said bracket being shaped to lie adjacent ah interior wall of said casing throughout its 10 length.

In witness whereof, I have hereunto subscribed my name in the presence of two wit nesses.
